A little follow-up by volkov

Well I did test drive loops of both the reg. Highlander and the Hybrid. Did the work-home leg. Wait 20 mins then home-work and back to the dealer which is less than a mile away. Both vehicles were cold and hadn't been driven for 2 days. Temp was 34F, but that was the high for the day and it had been sub-freezing for close to 24hrs preceding the test (10F overnight). Around here, we call that Spring weather.
Results come only from the on-board computer readings which I know aren't perfectly accurate but they are all I had. Hit all the same lights as luck would have it, although I did have to go through amber for one and slow down a little early to stop at another to keep it even.
Hybrid 10.6L/100km (22.1 mpg) and I forgot to set to ECON mode for the drive from work to home.
Highlander Limited 16L/100km (14.6 mpg).
Both were as expected well below EPA but the relative economy difference was maintained. That would mean about $800 per year gas savings at current prices for us on top of the gov't rebate and tax break. It actually makes the HY financially worthwhile in less than 5 years of use .

MPG and Cruising Range by stanwagon
Feb 22, 2008 (12:31 pm)

My "lifetime" MPG is for 2000 miles all at high altitude and in generally cold weather, and on hills. And the reading is about 23.3. I expect much better in summer, though I will drive it less. Unlike the Prius, the panel tells you lifetime MPG and MPG since last fillup (one can reset the lifetime to start over if one wants).
 
Another note: The "Cruising Range" tells how many miles more one can drive. I believe when that is 0 one would still have about 1.5 gallons in the tank. My last fillup the cruising range was down to 2 miles left and the tank took 14.55 gals, when capacity is, I think, 17.2. Hmm.. maybe 16.2? I am out of town and cannot check. But it seems like one can easily drive to cruising range of 0 with no fear of running out of gas.

"Nothing in the owner's manual indicates that reverse is all electric."
 
The HSD is only geared for forward motion. Reverse is electric. You might check the Prius board for a further discussion.

tire pressure by stanwagon

I believe there is no correlation. This must be because the data comes from a coded transmitter on the tire, which could be moved to another location.

Tire pressure warning only by hlander

That mean the tire pressures display in the Multi Functional Display randomly and if there is some warning about tire pressure we may not know right away which tire is going bad. And it's hard to read spare tire pressure with tire pressure guage.
 
Anyway , thanks for your reply Stanwagon.

1. The Prius is FWD while the HH is AWD.
2. I can tell at times that the ICE is powering the front wheels while in reverse.

On our '06 HH AWD, the energy flow display shows the hybrid battery pack driving all four wheels when reversing. The ICE comes on to charge the battery pack when necessary. We have never yet seen the display showing the ICE driving the wheels when reversing. The display may not show complete info, that's possible or '07-'08 HH may be different.

" I can tell at times that the ICE is powering the front wheels while in reverse."
 
Just because the ICE is running does not mean it is providing power to the rear wheels.
 
Take a look under the vehicle and see if there is a transfer case attached to the rear wheels, or if there are electric motors. I suspect you will find the latter.
 
The HSD is a completely different system than the transmission / engine used in the conventional HH.

"Take a look under the vehicle and see if there is a transfer case attached to the rear wheels, or if there are electric motors. I suspect you will find the latter. "
 
Of course the ICE does not drive the rear wheels, there is no transfer case or drive shaft to the rear. However, that does not mean that the ICE cannot power the front wheels in reverse. How would you drive this car if the traction battery pack failed (something I hope does not happen for 200K miles or so)? Do you think Toyota would produce a vehicle without the ability for the ICE to back the car?
 
Or even more simply, if the traction battery is below the cutoff point for use (40% charge?), the ICE would power the front wheels.
